How Zillow Makes its Money: Revenue Breakdown (2024)

How Does Zillow Make its Money?

Zillow Group, Inc. (NASDAQ: Z / ZG) generated $2.20 billion in revenue in full-year 2024 — up +12.8% from $1.95B in 2023 — by operating the most-visited real estate marketplace in the United States, with approximately 230 million monthly unique users across Zillow, Trulia, HotPads, and ShowingTime+. Zillow’s core business is monetizing the enormous gap between its user scale and real estate industry participants (agents, mortgage lenders, property managers) who need to reach those buyers, sellers, and renters.

Zillow earns revenue by selling advertising to real estate agents who want to be featured alongside listings (Premier Agent), charging property managers and landlords to advertise rental units and screen tenants (Rentals), originating home purchase mortgages directly (Zillow Home Loans), and selling software and technology to real estate professionals (ShowingTime+, Follow Up Boss CRM, Listing Showcase). The business operates at 76%+ gross margins — a clear indicator that Zillow is fundamentally an advertising and software business with real estate clothing, not a real estate company.

The FY2024 story has three major themes: (1) the housing market remained deeply suppressed by the highest mortgage rates in two decades (30-year fixed averaging 6.8–7.2% through 2024), creating a structural headwind for Zillow’s transaction-linked revenue — and yet the company still grew +12.8%; (2) the Rentals segment emerged as the highest-growth vector (+32.5%), validating Zillow’s bet that the rental marketplace could diversify its income beyond the cyclical for-sale market; and (3) Zillow Home Loans grew +58.3% as the company’s “housing super app” strategy — connecting the home search → mortgage → closing workflow in one seamless experience — gained tangible traction. Zillow is building toward the day when a rising-rate headwind reverses, and the company captures a dramatically larger share of the $100B+ real estate brokerage and finance ecosystem it sits atop.

Key Takeaways

• Zillow generated $2.20B in revenue in 2024 (+12.8% YoY) despite the most challenging US housing market in 30 years — existing home sales fell to approximately 4.0–4.1 million annualized units in 2024 (down from 6.1 million in 2021); the company grew revenue despite suppressed transaction volume by expanding rentals, mortgage, and technology services revenue; when the housing market recovers to 5.0M+ transactions annually, Zillow’s revenue upside is substantial
• Premier Agent (real estate agent advertising) remains the revenue anchor at ~52% of total ($1.15B), selling agents “buyer connections” in their target ZIP codes; agents pay on a flexible cost-per-lead model or a share-of-transaction basis (the Flex program); Zillow’s key value proposition is that it sits at the top of the home search funnel — most home buyers visit Zillow before ever contacting an agent, making Zillow’s ad inventory uniquely valuable in real estate
• Rentals ($530M, +32.5%) is the fastest-growing segment and is less cyclical than the for-sale residential market; rentals growth is driven by multifamily property manager advertising, tenant application fees (Zillow screening), and property management technology; the addressable market is large and underpenetrated — the US has 50M+ rental units, and professional property management software is fragmented and ripe for consolidation
• Zillow Home Loans (+58.3%) is the highest-strategic-importance growth segment; mortgage origination is the single highest-value transaction in the real estate chain, and Zillow’s ability to capture loan origination fee + gain-on-sale economics from users who found their home on Zillow is the core of the “housing super app” vision; Zillow’s mortgage attachment rate (% of Zillow buyers who use Zillow Home Loans) is still low (~3–5%), meaning the growth runway is enormous if the funnel conversion can be improved
• iBuying exit was the right decision: In 2021, Zillow shut down Zillow Offers (its direct home-buying program) after losing $881 million in a single quarter due to algorithmic pricing errors in a rapidly moving housing market; this was widely considered Zillow’s worst strategic mistake; in hindsight, the exit proved correct — competitor Opendoor has struggled with consistent losses and capital destruction, and the economics of direct home-buying have proven structurally difficult; Zillow refocused on its high-margin asset-light model
• Housing super app vision: Zillow’s strategic goal is to be the single platform where home buyers search for homes (Zillow.com), tour homes (ShowingTime+ scheduling, 3D Home tours), get pre-approved and close on a mortgage (Zillow Home Loans), and manage the transaction (Follow Up Boss CRM for agents, digital closing tools); if Zillow can increase its share of mortgage originations from ~3% of its buyer traffic to 10–15%, the revenue opportunity is $500M–$1B+ in additional annual mortgage revenue
• Structural housing market tailwind when rates normalize: The “lock-in effect” — where homeowners with 3% mortgages refuse to sell and trade up (locking in a 7% mortgage in the process) — has suppressed existing home sales to 30-year lows; every 50bps of mortgage rate decline historically correlates with ~500K additional home sales per year nationally; as rates normalize toward 5.5–6%, Zillow’s Premier Agent advertising revenue would grow substantially with no additional user acquisition cost

Zillow (Z) Business Model

Zillow operates a two-sided real estate marketplace connecting home buyers/renters/sellers with real estate agents, property managers, and lenders. See the Marketplace Business Model for the core framework.

Why Zillow’s marketplace position is defensible:

Zillow has the most powerful real estate data network effect in the US market: 230M+ monthly users visit Zillow to search for homes → this traffic attracts real estate agents and property managers who advertise to reach these users → agent advertising dollars fund continued product development and marketing that maintains Zillow’s traffic lead → the cycle reinforces itself. The “Zestimate” (Zillow’s automated home valuation model, available for 100M+ homes) is a primary reason users return to Zillow even when not actively buying — homeowners check their Zestimate regularly, generating returning visits and long-term brand affinity.

Revenue model for each customer type:

Premier Agent economics in detail:

Premier Agent is Zillow’s core product. When a user searches for homes in a given ZIP code on Zillow, they see agent advertisements alongside listings. Agents pay to be featured in those results. The economics:

• Traditional Premier Agent: Agents pay per “connection” (a buyer who contacts them through Zillow) in a ZIP code; pricing varies by market competitiveness — in a high-demand coastal ZIP code, a connection may cost $50–100; in a lower-demand market, $15–30
• Flex Program: Instead of paying upfront per connection, agents pay Zillow a referral fee (typically 35–40% of their commission) only when a transaction closes; this aligns Zillow’s revenue with actual transaction completion and is preferred by agents with cash-flow constraints
• Listing Showcase: A premium product ($200–300/month) that gives sellers’ listings enhanced photography, video tours, and prominent display, charged to the listing agent as an upsell

The lock-in effect and why 2024 was uniquely difficult:

From 2020–2021, approximately 12–13 million US homeowners refinanced their mortgages to 2.5–3.5% rates. Those homeowners are now “locked in” — selling their home means giving up a 3% mortgage and taking on a 7% mortgage, increasing their monthly payment by 50–70% on an equivalent home. This has suppressed listings to historic lows, reducing the number of home sales that generate Premier Agent lead opportunities. When rates normalize and the lock-in effect loosens, Zillow’s transaction volume (and advertising demand) will grow sharply.

Zillow Competitors

Real estate marketplace:

• Airbnb — competes in the rental/short-term accommodation space; Airbnb has disrupted long-term rental demand in some markets, affecting both Zillow’s rental marketplace supply and rental pricing dynamics; Airbnb also represents an alternative monetization model for property owners that redirects inventory from Zillow’s long-term rental marketplace
• Booking Holdings — operates in the broader housing/travel-adjacent marketplace; not a direct Zillow competitor for residential real estate but operates comparable marketplace/platform mechanics and competes for property owner mindshare in the short-term rental category
• Realtor.com (News Corp / Move, Inc.) — Zillow’s most direct portal competitor; second-most-visited real estate site in the US with approximately 80–90M monthly users; Realtor.com has access to MLS (Multiple Listing Service) data faster than Zillow (as the official NAR-licensed portal) but has never matched Zillow’s brand recognition or user traffic; News Corp has discussed spinning off Realtor.com multiple times
• Redfin (now acquired by Rocket Companies, 2024) — Redfin operated as both a portal (home search) and a brokerage (employing its own agents at reduced commissions); the hybrid model generated portal traffic while also capturing brokerage commissions; Redfin’s acquisition by Rocket Companies (the mortgage giant behind Rocket Mortgage) creates a potential competitor with the full transaction stack: portal + brokerage + mortgage

Mortgage:

• Rocket Companies — the dominant direct-to-consumer mortgage originator (Rocket Mortgage); Rocket’s acquisition of Redfin creates a vertically integrated competitor: Redfin portal (home search) + Rocket Mortgage (origination) + Rocket’s title and closing services; this is the most direct competitive threat to Zillow’s housing super app strategy; Rocket can now offer the same search-to-close experience Zillow is building
• Intuit (Credit Karma, Mint) — not a direct mortgage competitor but operates in the adjacent financial services lead generation space; Credit Karma provides financial product comparisons (including mortgages) to 130M+ members and represents competition for financially-minded home buyers who start their mortgage research with Credit Karma rather than Zillow

PropTech/InsurTech adjacent:

• Lemonade — AI-first insurance company offering homeowners insurance; relevant because homeowners insurance is a required component of every home purchase, and Zillow’s housing super app vision could extend to insurance referral/distribution; Lemonade’s technology-driven underwriting and instant-quote product represents the type of adjacent service Zillow could distribute within its platform

Agent technology:

• CoStar Group (Homes.com) — CoStar (commercial real estate data) has invested $1B+ in building Homes.com as a competing residential portal; CoStar’s strategy emphasizes agent-centric listing presentation vs. Zillow’s buyer-centric model; CoStar is spending aggressively on marketing to gain portal traffic share, representing the first well-capitalized direct challenge to Zillow’s portal position in years

Revenue Breakdown

Financial data sourced from Zillow Group 2024 Annual Report (10-K).

Residential — $1.15B (52% of Revenue, +10.6% YoY)

The Residential segment encompasses Premier Agent advertising (the flagship product), ShowingTime+ (scheduling and touring technology), Follow Up Boss (CRM software for agents, acquired for $399M in 2023), and Listing Showcase. Premier Agent alone accounts for the vast majority of this segment.

Premier Agent reach and scale:

• Approximately 100,000+ real estate agents purchase Premier Agent advertising on a recurring basis
• The US has approximately 1.5 million licensed real estate agents; Zillow has only penetrated ~7% of agents as paying advertising customers, suggesting significant expansion potential as the value proposition strengthens
• Average spend per agent varies widely — a top-producing agent in a competitive market may spend $5,000–20,000/month on Premier Agent; a smaller market agent may spend $500–1,000/month
• Zillow influences approximately $140B+ in annual home sales through its agent connections — the “take rate” on this influenced commerce (advertising revenue ÷ influenced home sales) is approximately 0.8%, very low vs. what a pure transaction platform would earn

ShowingTime+ and the touring funnel: ShowingTime is the scheduling backbone of the US real estate industry — used by 90%+ of MLS systems to manage showing appointments. This gives Zillow a privileged position in the mid-funnel (between home search and offer) and data on which properties get the most tour requests, a leading indicator of purchase intent. ShowingTime+ (the premium version) adds 3D Home virtual tours, AI-enhanced floor plans, and listing analytics.

Rentals — $526M (24% of Revenue, +32.5% YoY)

Rentals is the most strategically important growth segment because it is: (a) less cyclical than the for-sale market (people always need to rent, regardless of mortgage rates), (b) growing rapidly as the US renter population expands, and (c) significantly underpenetrated — Zillow’s current rental market share is large on traffic but smaller on monetization.

Rental revenue streams:

• Multifamily advertising: Property management companies and apartment communities pay Zillow to advertise available units on Zillow, Trulia, and HotPads; pricing is typically a monthly listing fee or cost-per-lease model
• Rental applications: Zillow charges renters ~$29 per application (credit check, background check, eviction history); landlords may cover this or require tenants to pay; as Zillow’s rental marketplace grows, application volume drives this revenue
• Property management software: Landlord tools — lease management, maintenance request tracking, rent collection — offered as a SaaS subscription; this product category is in early-stage development for Zillow and is a long-term opportunity to replicate what DocuSign and similar platforms earn from the document/workflow layer of real estate

The renter demographic opportunity: The US renter population has been growing — homeownership rates fell during the high-rate environment and many millennials who would have bought homes at age 28–34 are still renting at 32–38 due to affordability constraints. This structural increase in long-term renters (not just waiting-to-buy renters) expands the total addressable market for rental marketplace advertising.

Mortgages — $194M (9% of Revenue, +58.3% YoY)

Zillow Home Loans is the most strategically important segment for long-term value creation, even though it is currently the smallest by revenue. The economics of mortgage origination are exceptional: originating a $400,000 home loan generates approximately $4,000–8,000 in revenue (1.0–2.0% of loan amount including origination fees and gain-on-sale), compared to a Premier Agent connection that might generate $50–100 in advertising revenue that leads to a commission of $8,000–16,000 that Zillow doesn’t capture.

Mortgage attachment rate — the key metric to watch: If Zillow’s 230M monthly users represent a significant portion of US home buyers (Zillow estimates it reaches approximately 85% of people who move in the US), and if ~4M homes sold in 2024 × 85% reach = ~3.4M transactions influenced by Zillow, and if Zillow closed approximately 15,000–20,000 mortgages (implied by ~$194M at $8,000–10,000/loan), then Zillow’s mortgage attachment rate is approximately 0.5–0.6% of influenced transactions. Growing this to 3–5% — which Rocket Mortgage achieves as a dedicated mortgage brand — would generate $1B+ in annual mortgage revenue. This is the core of the housing super app monetization thesis.

Enhanced Markets program: Zillow’s Enhanced Markets program bundles Premier Agent connections with Zillow Home Loans — agents who participate in Enhanced Markets get access to a combined buyer lead that includes a pre-approved mortgage from Zillow Home Loans. This creates a unique value proposition: agents get buyers who are already pre-approved (reducing the risk of deal failure from financing issues), and Zillow captures the mortgage origination revenue on the same transaction where it earns the advertising revenue.

Revenue Trend (3-Year)

Note: 2022 mortgage revenue was significantly higher before Zillow Home Loans restructuring post-iBuying exit.

The trajectory shows a business stabilizing after the iBuying catastrophe: Operating losses narrowed from -$400M+ (2022) → -$101M (2023) → +$40M (2024) while revenue recovered and began growing. The Rentals segment has been the most consistent grower across the entire period, growing from $0.33B (2022) → $0.40B (2023) → $0.53B (2024) — a +61% cumulative increase in two years.

Zillow (Z) Income Statement

Financial data sourced from Zillow Group SEC filings.

The most important line: operating income turned positive (+$40M) for the first time after years of operating losses — driven entirely by revenue growing faster than the largely fixed operating cost base. Technology & Development spending (+4.3%) grew far slower than revenue (+12.8%), demonstrating emerging operating leverage. Sales & Marketing grew only +1.6% vs. +12.8% revenue — Zillow’s brand strength and organic traffic make incremental marketing spend largely unnecessary. As revenue continues growing while operating costs stay relatively fixed, operating margins will expand toward 10–15% over the next 3–5 years.

Gross margin stability at 76.1% confirms the advertising + software model generates structurally high margins. The slight -60bps compression reflects growth in the mortgage segment (lower gross margin than advertising) becoming a larger mix of revenue — a healthy tradeoff.

Zillow (Z) Key Financial Metrics

• Gross Margin: 76.1% — Structurally high, reflecting the advertising and software nature of Zillow’s core business; Premier Agent advertising has near-zero marginal cost of delivery (showing an agent ad to one more user costs Zillow nothing); the slightly lower margin of the mortgage segment creates a modest blended margin drag as that segment grows; long-term, gross margin should remain 74–78% as the mix of high-margin advertising and software offsets low-margin mortgage origination

• Operating Margin: 1.8% — Just turned positive in 2024; the path to 15–20% operating margin (which is achievable given Zillow’s software-comparable cost structure) runs through: (1) housing market recovery adding $400–600M in Residential segment revenue with minimal incremental cost; (2) Rentals continuing +25–30% annual growth; (3) Mortgage attachment rate growing from 0.5% to 3%+ of influenced transactions; watch operating margin expansion as the single best measure of the housing super app strategy’s financial execution

• Free Cash Flow — Zillow’s FCF has been volatile due to the iBuying wind-down; in 2024, FCF turned positive for the first time in several years; the asset-light model (no inventory, no balance sheet risk from housing prices) means Zillow’s capex is predominantly technology investment (capitalized software development), and the business should be a strong FCF generator at scale; management has used FCF for share repurchases rather than dividend initiation

• Monthly Unique Users: 230M+ — The most important leading indicator of Zillow’s competitive position; Zillow’s user advantage is 2–3x its nearest competitor (Realtor.com); maintaining and growing this traffic lead requires continuous product improvement (AI search, better mobile experience, Zestimate accuracy); any sustained decline in relative traffic market share would be an early warning signal of competitive erosion

• Mortgage attachment rate — Not formally disclosed but calculable from disclosed loan count and revenue; track the implied attachment rate quarter-over-quarter as the clearest signal of housing super app strategy execution; Zillow’s thesis requires growing from ~0.5% to 5%+ attachment rate over 3–5 years

Is Zillow Profitable?

No — on a GAAP net income basis, Zillow reported a net loss of $20 million in 2024 (net margin: -0.9%). However, the company turned operating income positive ($40M, +1.8% operating margin) for the first time, representing a dramatic improvement from -$101M operating loss in 2023. The net loss is primarily driven by interest expense on convertible debt and income tax timing items. Adjusted EBITDA (the metric management emphasizes) was positive and growing through 2024. Zillow’s trajectory — operating losses narrowing from -$400M+ (2022) to +$40M (2024) — demonstrates a business rapidly approaching sustainable GAAP profitability. The housing market recovery, when it comes, will accelerate this trajectory substantially.

What to Watch

1. Mortgage rate trajectory and housing transaction volume — The single biggest driver of Zillow’s revenue upside is mortgage rate normalization; 30-year fixed rates falling from 7%+ to 5.5–6% would likely add 500K–1M existing home sales nationally; every 100K additional annual home sales represents approximately $30–50M in additional Zillow Premier Agent advertising revenue at current take rates; watch weekly Mortgage Bankers Association purchase application data as the leading indicator of housing market recovery

2. Mortgage attachment rate growth — The percentage of Zillow buyers who use Zillow Home Loans is Zillow’s most important internal operational metric; management has guided toward growing this rate through the Enhanced Markets program (bundled Premier Agent + pre-approved mortgage); any quarter where mortgage revenue growth significantly outpaces the housing market recovery implies attachment rate improvement — which would signal that the housing super app strategy is genuinely converting

3. Rentals segment margin and product expansion — Rentals is growing at +32.5% but management has not disclosed segment-specific profitability; watch for Zillow to introduce higher-margin property management software products (rent collection, maintenance tracking, tenant communication tools) alongside its current listing advertising; if Zillow can grow rental software revenue alongside advertising, the segment’s margin profile improves substantially; the addressable market (50M+ US rental units) vastly exceeds Zillow’s current penetration

4. CoStar (Homes.com) competitive threat — CoStar has committed $1B+ to build Homes.com into a viable Zillow competitor; CoStar’s strategy of paying agents to control their own listings (vs. Zillow’s buyer-centric model) is a genuine differentiation attempt; watch Zillow’s monthly unique user count for any sustained downward trend, which could signal that CoStar’s marketing spend is capturing share; Zillow’s 230M monthly users vs. Homes.com’s significantly smaller user base is a large competitive moat, but moats erode if one side stops investing

5. Rocket Companies integration of Redfin — Rocket’s acquisition of Redfin creates the only vertically integrated competitor to Zillow’s housing super app: home search (Redfin) + mortgage (Rocket Mortgage) + title and closing (Amrock); if Rocket successfully integrates Redfin’s portal traffic with Rocket Mortgage’s origination funnel, it could become the first real end-to-end alternative to Zillow’s strategy; watch Redfin’s traffic trends post-acquisition as an indicator of Rocket’s integration execution

6. AI-powered search and personalization — Zillow has been building natural language search (“3-bedroom homes near good public schools, quiet neighborhood, under $550K in Austin”) and AI-powered home recommendations; if AI search meaningfully improves home buyer experience, it reinforces Zillow’s traffic lead; it also may shorten the home search process, reducing the number of agent contacts per buyer and potentially affecting Premier Agent advertising economics — a risk to watch alongside the opportunity

Zillow (Z) Financial Summary

Zillow Group (NASDAQ: Z) generated $2.20 billion in revenue in 2024 (+12.8% YoY) across Premier Agent residential advertising ($1.15B), Rentals ($526M), Zillow Home Loans mortgage origination ($194M), and technology/data products — with 76.1% gross margin reflecting its advertising and software-first business model. The company achieved positive operating income ($40M) for the first time in 2024, and the trajectory toward meaningful profitability depends on two independent variables: the pace of housing market recovery (mortgage rate normalization) and the rate of mortgage attachment improvement (housing super app strategy execution). Rocket Companies’ Redfin integration and CoStar’s Homes.com investment represent the most credible competitive challenges in years, but Zillow’s 230M monthly user lead and Premier Agent network effects remain formidable advantages.
